Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to a medical multi-angle mouth mirror for stomatology department.
Background
the mouth mirror is one of the most common small-sized medical instruments in oral clinical diagnosis and treatment, and has the main functions of: pulling the patient's cheek and pushing the tongue to facilitate direct visualization of the lesion; the light rays are gathered, and the visibility of the examined part is increased; the parts which are difficult to look directly are observed by the mirror reflection light rays, such as the upper teeth and the inner part of the pulp cavity. However, the current oral mirror body commonly used in clinic is connected with the handle through a fixed angle, for example, the mirror body and the handle form an included angle of 150 degrees, or the mirror body and the handle are in the same plane, and have no self-contained light source, and all provide light through the reflection dental chair illuminating lamp. When the mouth mirror is used for observing parts which are difficult to look directly, such as the cheek and palate sides of the maxillary dental crowns, the near and far middle necks, the insides of the marrow cavities of the upper and lower jaw teeth and the like, the angle of the mouth mirror, the body position of a patient and the angle of a dental chair illuminating lamp are frequently required to be repeatedly adjusted, so that the observation and the operation of doctors are obviously influenced, the treatment time is prolonged, and the comfort level of the patient is reduced. Therefore, the fixed-angle mouth mirror cannot realize multi-angle observation and cannot be well adapted to various use scenes.
In addition, in the using process of the mouth mirror, the temperature difference exists between the mouth mirror and the oral cavity, so that the mirror surface is fogged, and the observation is influenced; when a high-speed turbine mobile phone is used for removing decayed tooth decayed matter, temporary sealing materials of cavities or preparing crowns and grinding away enamel and dentin, the decayed matter, the temporary sealing materials, the enamel or dentin crushed powder are adhered to the mirror surface of the mouth mirror along with water mist, and the observation and operation of a doctor are obviously influenced. At present, the problem of fogging of the mirror surface is solved, and when the mirror surface is cleaned, the mouth mirror needs to be taken out of the oral cavity of a patient and is wiped by using a sterile cotton ball. After the treatment in the mode, a doctor needs to adjust the angle of the mouth mirror again to observe or treat the affected area, and repeatedly 'take out the mouth mirror, wipe and put the mouth mirror into the oral cavity and adjust the angle', so that the treatment efficiency is reduced, and the treatment time and the discomfort of a patient are increased. And after simple wiping, the mirror surface is easy to be fogged again, and is also easy to be adhered with decayed matter, temporary sealing objects, enamel or dentin again, and a patent publication No. CN 105816145B discloses a multi-angle adjustable mouth mirror, which blows off the stains adhered on the surface of the mouth mirror by blowing air to the surface of the mouth mirror, and the effect of removing the stains of the mouth mirror is poor.
